108 I tried but I did is 180 divided it by 5 giving me 36 next I did 36 times 3 giving me 108. And I apologize if I got it wrong I tried.
Step-by-step explanation:
We only know 1 side, and that is the width of 4. We only have the diagonals at our side. Half of the diagonal is 5. As a result, the diagonal is 10. I want you to imagine a triangle that has a base of 4 and a hypotenuse of 10. Use the Pythagorean Theorem to find b, or the height.
a² + b² = c²
4² + b² = 10²
16 + b² = 100
100 - 16 = 84
b² = 84
b = √84
b ≈ 9.165
Now we know the length of the rectangle, which is about 9.165. Multiply that by 4 to get the area.
9.165 * 4
36 + 0.4 + 0.24 + 0.020
36.4 + 0.24 + 0.02
36.64 + 0.02
36.66 u²
The area of rectangle RSTU is about 36.66 units squared.
Answer:
Step-by-step explanation: The area of a circle can be found with the equation A=(pi)*r^2. Use the equation to find the answer:
A=(pi)*5.5^2 (or A=3.14*5.5^2)
A=94.99 or 95.03 in exact pi
Have a nice day! :)
Answer:
5,400
Step-by-step explanation:
225 / 2 = 112.5
112.5 x 2 = 225
225 x 20 = 5,400
